Tsang Kin-shing, known as 'the Bull', is to quit the Democrats, further widening the rift between the party's Young Turks and mainstream factions. Mr Tsang, a leader of the Young Turks, plans to announce today that he will run on his own for a Legco seat in the Hong Kong Island constituency. Last Sunday, the party voted against putting him on its candidates list for the constituency. Mr Tsang said the vote had prompted him to make the 'painful decision to quit the party' and stand on his own. 'I would breach party rules if I stood for election under the banner of the Democrats as I was not on the endorsed list,' he said. 'I don't want to adversely affect the support the Democrats get.' Mr Tsang, who got his nickname from his strident street protests and physical presence, became a Legco member in 1995, representing the Primary Production, Power and Construction functional constituency. He was ousted with other Democrats during the handover and he did not run in 1998. Party whip Szeto Wah said yesterday he had asked Mr Tsang not to badmouth the Democrats. 'Gentlemen should not badmouth each other if they cease to be friends,' he said. Mr Tsang was adamant he had a better chance of election following Citizens Party legislator Christine Loh Kung-wai's decision not to seek re-election. He said the vacated seat should not fall into the hands of the conservative forces. Contenders for the five Hong Kong Island geographical seats include the Democratic Party's Martin Lee Chu-ming and Dr Yeung Sum and the Democratic Alliance for the Betterment of Hong Kong's Gary Cheng Kai-nam and Choy So-yuk. Other likely candidates are Ronald Arculli of the Liberal Party; district councillor Ronald Fung; solicitor Paul Tse Wai-chun; chief secretary of the Hong Kong and Kowloon Trades Union Council Jim Lee Kwok-keung; and district councillor Jennifer Chow Kit-bing. Mr Tsang, a standing committee member of the Hong Kong Alliance in Support of the Patriotic Democratic Movement in China, thought he could grab about five per cent of the votes according to a poll he conducted earlier this year. Ms Loh's decision to stay out of the race would boost his votes to the 11 per cent needed to win a seat, he said. Mr Tsang said he had told party chairman Mr Lee, Mr Szeto and vice-chairman Albert Ho Chun-yan of his decision. 'I respect uncle Wah very much. He has enlightened me a lot and they are very understanding. It was only Yeung Sum who did not want me to be on the list. He has used a lot of proxy votes to oust me,' he said, adding he disagreed with Dr Yeung on several issues. Mr Tsang said it was strange the Democrats had decided to field two lists of candidates in New Territories East but not on Hong Kong Island. He said he had been given no other choice but did not rule out co-operating with the Democrats in the future. 'After all, the Democratic Party is the best political party in Hong Kong and its stance on democratic pace is very firm,' he said. Neither Dr Yeung nor Mr Lee could be reached for comment.
